A blood sugar level of 140 mg/dL (7.8 mmol/L) to less than 190 mg/dL (10.6 mmol/L) signals the need for a three-hour glucose tolerance test to diagnose gestational diabetes. A blood sugar level of 190 mg/dL (10.6 mmol/L) or higher indicates gestational diabetes.
The one hour oral glucose challenge test [GCT] is a screening test for gestational diabetes that measures plasma or serum glucose concentration 1 hour after a 50-g oral glucose load. A blood sugar value >140 mg/dl (7.8 mmol/l) identifies approximately 80% of women with gestational diabetes (GDM), a cutoff of >130 mg/dl (7.2 mmol/l) identifies ...
